Key result
Stellate ganglion blockade remains recommended for refractory electrical storm despite unclear predictors of procedural success.
Why the study?
While stellate ganglion blockade is effective for electrical storm, less is known about factors that may mark or predict procedural success.
May reduce refractory electrical storm episodes; leaves open ECG predictors for prospective validation.
Electrical storm (ES) is a cardiovascular emergency defined by ≥3 episodes of sustained or treated ventricular tachycardia or fibrillation (VT/VF) separated by ≥5 minutes within 24 hours.1 Treatment of ES is challenging. Consensus guidance from the European Society of Cardiology recommends stellate ganglion blockade (SGB) when ES is refractory to beta-blockers and amiodarone.1 While SGB has been shown to be an effective treatment for ES, less is known about what factors may help mark or predict procedural success.

Barrett et al. (2026) studied Electrical storm. Stellate ganglion blockade was evaluated. Stellate ganglion blockade is recommended for refractory electrical storm, though factors predicting procedural success remain unclear.
